Saw this kit at the Sand Sports Super Show. Very interesting. Not quite sure about the shock positioning, but I do like the brackets that they have done. It was in the Rigid Industries booth. RI said that FST made the kit to their specifications.
There were no less than a dozen RZR long travel kits at the show. What I liked is they were all pretty different - so far. Now comes the copy cats.
